Isn't the VA "power" limit frequency dependent?  The higher the switching frequency, the higher the Volt-Ampere rating for a given transformer, motor and such.  As long as the core is not in saturation, the transformer is good to go for higher V-A levels.

Well, if you're thinking of 12-0-12  primary driven  by switched dc, won't you have 2 outputs each of (2 x 115  ) ? Which you can stack or parallel as needed. Then you can  reckon your max output current from that to fit safely in the <30 VA limit.
